This short course explains how a reciprocating compressor works by focusing on the pressure-volume diagram and the governing fundamental thermodynamic principles - but not in an overly academic way.  This will include discussions of pressure-time and pressure-volume diagrams, volumetric efficiency, capacity, power, and compression efficiency.  In addition, it will cover the effects of changing conditions (pressures, rotating speed, thermodynamic properties, etc), gas analysis, temperature, and pulsation.  Mechanical design details will not be covered in any significant detail.   An understanding of the pressure-volume diagram and the basic thermodynamics is vital and forms a required solid foundation for a deeper understanding of the mechanical aspects.


Learning Objectives

  • The primary objective is to leave the course with a complete understanding of the pressure versus time and pressure versus volume diagram sequences.
  • Understand how a cylinder end’s capacity is derived and calculated from the pressure-volume diagram using volumetric efficiency.
  • Understand that the power required to compress a volume of gas is also derived from the pressure-volume diagram.
  • Understand that the power required to compress a certain volume of gas is a sum of adiabatic, valve loss and friction and how each is calculated.

Target Audience 

  • This workshop is great for design engineers and project managers who are responsible for compression projects and is good for both beginner and intermediate levels.

Event Summary

This 2-hour workshop will go over the fundamentals of vibration theory, followed by a discussion on best practices for making vibration measurements.  Using these basic theory and measurement techniques, several case histories will be presented and explained to help the attendees understand real-world applications of these principles.




Learning Objectives

  • Gain a working knowledge of basic vibration concepts (mass, stiffness, resonance, etc.).
  • Understand measurement procedures that greatly enhance the ability to evaluate vibration issues and communicate results.
  • Combine the knowledge of basic theory and good measurements to improve the real‑world success rate for solving vibration related problems.



Target Audience 

  • Engine Analysts
  • Mechanics
  • Entry Level Engineers
